gas mask March

Gas mask and his friend are in trouble and must march,because Mr space alien is angry at pig man and gas mask. Oh this is also my first real attempt at digital art, not the same as oil painting, or drawing but it is interesting. I used the program smooth draw 3 a free program. I also used the smudge tool a lot, it makes everything look trippy.
